BG allows for smaller skirmishes, where HW are less likely to succeed. I question the usage as sac paladin, the class is much more useful for devo support.

There is no strongest class in woe. WoE is more about depending on various different characters. A creo or high wizard would be useless without bragi, devo, etc. BG pretty much follows the same code as woe. Oh and do yourself and your team a favour BG and never play a melee class/builds like sacri pala.

Pre-renewal servers contains BG Supply which supplies acid bottles, I think Creator one of the strongest class in BG and PVP not the most but one. Champion prolly makes it to top 1 because of asura spam.
